The LectroFan Micro is more than just a sleep sound machine. This compact device also doubles as portable wireless speaker! Perfect for sleep, relaxation, study, and speech privacy, the Micro sports a unique design that allows you to swivel the speaker, adjusting the audio playback direction to be either upward or frontward. With this certified-refurbished model, you can get your hands on your own LectroFan Micro for a fraction of what it would cost new!
